Hello!
When I measure my tank I get 120 TDS, Gh 5, kh3.

Is it normal that relation between TDS and GH?

I have read that the most common relation is GH 3 = 120 TDS

I use 100% RO water for the water changes and I change 50%.

My seiryu stones increase gradually the TDS, Gh and Kh until I do the water change.

And another question, seiryu stone release calcium band magnesium in to the water, but I cannot find if it’s in the relation of Ca:Mg of 3:1 o 6:1 or 1:1

Any help will be much appreciated!

Thanks!
